cyano only on glass?

[xxoczukxx]

I have a red cyano issue but it only grows on my tanks glass.

The rock and sand are clear for the most part.

I can scrape it but it will come back. I have low nitrates and need a phos test kit. My fuge was doing well but around the time my chaeto stopped growing well/started receding the cyano seemed to start growing.

Could it be outcompeting or would this be due to some phos imbalance?

Photos would help.

If you have to scrape it, it's probably not cyano. Cyano typically is easy to blow off surfaces with a turkey baster, or suck out during water changes.

Upon closer look it doesn't even look like cyano. I have no idea what I have on my glass. If I scrape it off it comes back slowly after like a couple weeks.

Nothing eats Dinos. The best advice I can give you is get a cheap microscope and on the Dino tread the guys will ID it for you. Based on where it is you may only need as correctly sized UV but don’t take my word for it.
There are several strains of Dinos and the treatment is different.
In general check phosphate and nitrate. None should be 0.

Any second opinions? If its dinos I guess Ill have to deal with it somehow, I just find it so odd that its only on the glass

So, it was definitely dinos.

I started feeding reef roids about a week ago and today there are barely any dinos left and green algae is once again growing on my glass.

Maybe the reef roids raised nutrients enough for algae to get a hold and out compete the dinos.

I had bought a uv sterilizer to deal with them but I guess I can just sell it now
